the previous year there were 630 students 


To find the percent of a number first you have to convert it into a decimal. To convert it into a decimal move the point 2 places so it becomes .20 . Then you just multiply those two numbers (504 and .20) and you get: 100.80 So 20% of 504 is 100.8 so sice you are trying to find the number before the decrease you will add that to 504 ....I think. Result: 604.8
